A gentle formula designed to take care of you, and our planet.
Sometimes what you are not is as important as what you are.
Your average protein company, whether animal- or plant-based, will typically have a lot of marketing-heavy ingredients in their label. They include tiny amounts of trendy & hard-to-pronounce ingredients to give the perception of an elevated value without actually adding much other than the price tag.
Best case scenario, these extra ingredients add a nominal benefit to your body. Worst case, you’ve now added a dozen allergens and irritants to your daily routine, but in quantities so small you only notice after the inflammation begins to acc ...
Sometimes what you are not is as important as what you are.
Your average protein company, whether animal- or plant-based, will typically have a lot of marketing-heavy ingredients in their label. They include tiny amounts of trendy & hard-to-pronounce ingredients to give the perception of an elevated value without actually adding much other than the price tag.
Best case scenario, these extra ingredients add a nominal benefit to your body. Worst case, you’ve now added a dozen allergens and irritants to your daily routine, but in quantities so small you only notice after the inflammation begins to accumulate over time.
You become run down, your sleep is restless, your allergies are acting up, and it’s all happening for no apparent reason. Even worse, you don’t realize that it’s coming from the “superfood blend” in the protein you started 3 weeks ago, so you keep taking it and feeling worse.
It’s not just the weird fillers, either: a bunch of other not-so-great practices from the nutrition industry find their way into what you put in your body too. It may be profitable... but that doesn't mean it's right.
We refuse to conform to that status quo. That means no fillers or irritants, no serving size illusions, no fake flavors, and no allergens.
What we DO have is 5 meaningful ingredients, with 100% purity, full transparency, and sourced only from the best of the best.

Our perfect, complete cell-based protein is derived from non-GMO baker’s yeast and purified water, unlike plant- and animal-based proteins that are exposed to heavy metals, pesticides, and worse.
Soluble Fiber
Our hypoallergenic soluble fiber is organic Sunfiber™, the soluble fiber that is clinically backed for supporting gut health and both types of IBS.
Probiotics
Most probiotics do not survive manufacturing or digestion, but LactoSpore™ is a carefully-selected strain of the spore-forming probiotic Bacillus Coagulans, which naturally endure the manufacturing and digestion processes.
Organic Monkfruit
Preferred healthiest non-nutritive sweetener, even Generally Recognized as Safe (GRAS) for use during pregnancy.
Salt
Just a dash for enhanced flavor and electrolytes.

Why should I have a Spacemilk subscription?
There are a few reasons many customers prefer a Spacemilk subscription.
- Our subscribers receive free shipping for the life of their subscription, as well as increased discounts: all subscription orders ship with free shipping for the life of the subsription, but in order to help you fully keep Spacemilk part of your daily routine, the second shipment also receives 5% off, and then the third and every subsequent shipment in the subscription receives 10% off.
- Spacemilk is made in smaller batches to ensure purity; therefore, there is only so much Spacemilk available with each run. Subscriptions receive priority, and are the best way to make sure you never run out of Spacemilk.
- Subscriptions are flexible in frequency and quantity, and the quantity discounts are in addition to subscription discounts.
We know that making Spacemilk a part of your daily routine will help you feel great, and want to help you stay feeling that way!
